The X3D library is used to load an X3D file and render it using OpenGL (an X3D file is an XML file describing a 3D environment that can be rendered with OpenGL.)
The library supports all the objects as defined in the X3D specification in 2006. The render library is still somewhat limited, though. It works well under Linux. It is likely to work on any Unix, and has worked under MS Windows before. The project includes a test that makes use of FLTK version 2.0-m3. That version of FLTK can be downloaded from the project repository, as FLTK itself actually ended up not publishing a concrete 2.0 version of the library.

FDRDF is a tool that builds a catalogue of descriptions in an RDF representation of the specified files. The descriptions currently include: file status (as per the stat system call); SHA-1 hash over the file contents; MIME type (as guessed by the file tool), geospatial metadata (as per GDAL), and GRIB file composition (as per GRIB API).

LiberORM is a class that can be used to store and retrieve objects as database records. It can take objects of arbitrary types and insert, update, and delete them in a database table according to mapping configuration.

The NetCDF package consists of a few tools to operate on NetCDF and, by utilizing the compatibility API, HDF4 files. The tools are intended to be used from shell scripts. They include a couple of simple shell wrappers over the respective NetCDF functions (ncattget and ncattput) and a more sophisticated ncget tool. The ncget tool delivers (for NetCDF) or complements (for HDF4) the functionality of the "hdp dumpsds" command. It allows a selected part of a NetCDF variable or an HDF4 scientific data set (SDS) to be extracted in either an ASCII or binary form, applying the transformation specified by the scale_factor and add_offset attributes. This tool allows one to feed the data of NetCDF variables (or HDF4 SDS) to other tools designed to operate on either ASCII (text) or raw (binary) data.

Common Lisp Quick Reference is a booklet with
short descriptions of the thousand or so symbols
defined in the ANSI standard. It comes with a
comprehensive index. It is written in LaTeX and
formatted for printing on both A4 and letter

can easily be turned into a handy booklet.

Arachne is program that implements Avidan and Shamir's seam carving technique for content-aware image resizing. It allows realtime, fluid image resizing using this fascinating technique. Seam carving works by removing the "boring bits" from an image, so it can change the aspect ratio of many images without changing the shape of the objects inside.

TextSearch is a program to search through a set of
text files in a directory structure. Each document
is searched using a regular expression and an
overview of the results is shown as a tree
structure. By clicking on a file, it can be
viewed, with matches being highlighted. As opposed
to other programs out there, its focus is not so
much on statistics, i.e. how often a word would
occur in an entire corpus of files, but rather on
occurrences in single files.
